Given numbers are 423, 520, 126, 141
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 520) = 219960
GCD(423, 520) = ( 423 x 520 ) / 219960
= 423 / 520
= 423
Step2:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
Step3:
LCM(1, 141) = 141
GCD(1, 141) = ( 1 x 141 ) / 141
= 1 / 141
= 1
So, Greatest Common Divisor of 423, 520, 126, 141 is 1
